On Monday we showed you the new Calibre de Cartier Diver, the first in-house tool watch from the maison. Today we have something for you from the opposite end of the spectrum. Here is the Rotonde de Cartier Astrocalendaire, a perpetual calendar with a flying tourbillon that uses a multi-tier circular display for the perpetual calendar and a mechanism that is almost entirely free from the typical levers and springs. This is a seriously complicated watch that introduces a number of important new technologies, plus it just looks like it means business.

Last year's SIHH saw the introduction of the Rotonde de Cartier Perpetual Calendar Chronograph, adding the benchmark pairing of complications to the Cartier stable. The perpetual calendar indicators are a bit nontraditional on this watch, with retrograde days at 6 o'clock and date around the perimeter of the dial. But the Astrocalendaire takes nontraditional to a totally different level.

The perpetual calendar indicators here are a set of three tiered rings that surround the central flying tourbillon with its signature C-shaped cage. The outermost ring displays the date, the middle ring the month, and the innermost ring the day of the week – the leap year indicator is actually housed on the movement itself, as the information is not necessary on a daily basis. Those small blue windows are actually protrusions from geared wheels that turn slowly as the various indicators advance. Time, date, and month are all set via the crown, while a simple corrector advances the day. The crown-adjusted functions go both backwards and forwards smoothly, something that can't be said of most perpetuals.

The reason for this is that most perpetual calendars use a series of levers and springs to store up power and advance the indicators. Not this perpetual calendar. The biggest innovation of the new in-house calibre 9459 MC is that the main functions are all controlled by gears instead of levers. In addition to allowing the wearer to set the watch in both directions, it greatly improves durability and reduces the risk of breakage. There is a special set of nested gears that Cartier is calling "the Brain," which is the central feature of this new movement, but we'll have more on that for you from SIHH 2014.

At 32mm wide and 8.1mm thick, the calibre 9459 has 51 jewels and 382 total components. It is automatically wound via the large winding rotor, which you can see through the caseback. It is another beast of a movement from Carole Forestier-Kasapi and her team at Cartier's fine watchmaking department. Just looking at this movement, you can tell it is not like your usual perpetual calendar.

The fully cased watch comes in at 45mm across and 15.1mm thick – this is no small, understated perpetual calendar. The case, crown, and bezel are all platinum, though the black alligator strap is held closed by an 18k white gold buckle. For a watch of this size, it sits reasonably well on the wrist, though I don't see this sliding under a cuff under any circumstances. Reading the circular mechanism becomes intuitive very quickly. In poor lighting, it's not the easiest to see, but that's a problem that plagues many complicated dials.

The Rotonde de Cartier Astrocalendaire is a limited edition of only 100 numbered pieces. Pricing is not yet official, but it should be around 150,000 Euro (a little over $200,000 at time of publishing). Visit Cartier for more.

This isn't a new watch, it was shown last year. And on top of that, all 50 pieces of Richard Mille's RM27-01 Rafa Nadal have long been sold. But, we had the chance to see the incredible light-weight, mega-casual watch yesterday and each time we come across one, it leaves us blown away.

Although Baume & Mercier is best known for its more affordable offerings, the brand is not limited to basic entry-level watches. At SIHH 2014, Baume & Mercier introduced its first tourbillon wristwatch, the Clifton 1892 Flying Tourbillon, combining the clean style of the other Clifton watches with a more exclusive complication. The name is a nod to the historic Baume & Mercier tourbillon pocket watch that served as inspiration and the watch really does bring something unexpected to the Clifton line-up. Here's a closer look at this horological curve ball.

In the weeks after SIHH, I am asked by more than a few different publications to recap the highlights (and low-lights) of the fair. My responses are, in some ways, rather predictable. If you've followed HODINKEE for any period of time, you know my personal proclivities tend to trend towards traditional watchmaking, refined, almost conservative design, and above all else, pure subtlety. So, each year my "Best Of" lists consist of things like a classic, ultra thin Tank from Cartier, something vintage-inspired by Jaeger-LeCoultre, a self-winding Royal Oak from AP, and whatever the latest is from Vacheron or Lange. These are my bread and butter watches, so to speak. But, for 2014, two watches that I keep finding atop my lists aren't from these mainstays of haute horology, but rather from a PEN company! Well, kinda. I'm talking about the Meisterstück Heritage Pulsograph and Perpetual Calendar from Montblanc. These are both really, really good watches, and in this post I'll take a close look at both – and above, you'll see me sit down with my good friend Frank Geelen of Monochrome to discuss the collection.

One of the most interesting complicated watches to come out of SIHH 2014 is without a doubt the Richard Lange Perpetual Calendar Terraluna from A. Lange & Söhne. It uses a regulator-style dial layout with the addition of a perpetual calendar, a 14-day power reserve, a constant force escapement, and a graphic orbital moonphase complication right on the plate of the movement. This is an absolute beast of a watch and here we have a ton of live photos and all the gritty details for you.

While we’ve seen chronographs from Panerai before, the Radiomir 1940 Chronograph is an all new design for 2014 presented in three metals: red gold, platinum, and white gold, each with a different dial. These decidedly retro-feeling dials combine with stylized hands and the classic cushion case to complete the 1940s aesthetic. In addition to the great looks, inside beats a modified Minerva movement that stands out among the rest. Although all three share a number of traits, each of these three limited editions is unique and brings something special to the mix. Picking a favorite certainly isn't easy.

For 2014, Jaeger-LeCoultre has introduced four new updates to their Reverso collection. Last week, we showed you the Grand Reverso Ultra Thin 1931 and today we’ll shed some light on the Grande Reverso Night & Day. The Night & Day still has all the traditional stylings of the classic Reverso collection which, quite frankly, need no update. This is an uncommon instance in which all of the necessary updates are internal: at the heart of this watch is a new automatic in-house movement. For an iconic piece in the watchmaking industry that has had numerous iterations and complications, this update stands above the rest by bridging the gap between tradition and modernity.

I'm calling it right now – within the first few hours of the opening of SIHH 2014 – this is going to be one of the coolest watches of the week. You're looking at the Montblanc Meisterstück Heritage Pulsograph, and if you know anything about the history of Montblanc, or great 20th century chronographs, you can guess where this is headed – in particular if you know what the little cursive "M" stands for on the dial. This. Watch. Is. Awesome.

It's getting to be that time of year again - SIHH is just around the corner. That means you're about to see a veritable bevy of the new hotness hit the 'Dinkee. We'll start with a new one from Audemars Piguet - the new Royal Oak Concept GMT with a dose of remarkable white ceramic. And that's not just on the case, either.

Ask your average millionaire independent watch collector who is making some of the most interesting and badass watches around, and there is a good chance they'll mention De Bethune. We stopped in to see the guys our first day in Geneva and already showed you their art piece, the Dream Watch 5. Now, we're back to their bread and butter – the DB28, this time with a jump hour called the "Digitale."

Among the six new watches released by Richard Mille at SIHH 2014, there was one that felt distinctly unlike the others – the new RM63-01 Dizzy Hands. We’ve come to know Richard Mille for the Swiss manufacture’s never-ending quest to push the technical boundaries of watchmaking (and the unarguably polarizing designs like the RM59-01 Tourbillon for Yohan Blake). Unlike other Mille timepieces, which are often inspired by high-level sports like F1 Racing and the aerospace industry, the Dizzy Hands takes conceptual cues from a poem called “Le Temps” by 19th century French poet Gérard de Nerval.
